What does Atriox have against the humans I mean sure we killed a lot of brutes in the first Halo games but those brutes were dumb enough to follow the profits so I doubt Atreox is avenging them and yes Cortana did destroy their Planet but that’s not directly our fault so what does Atriox’s problem with us
Its not what Atriox has against humans, Banished and UNSC paths aligned when Cortana blew up his planet. We were just in his way. No direct hate towards the humans.
